Tiles, of which the following is a specifi-.

cation. I

My invention relates to hollow earthenware building blocks or tile madeof clay,

gypsum and similar material, and the invention has particular referenceto a cellular block formed with a groove to hold a nailing strip towhich various kinds of interior trimming may be secured by'nails orscrews.

The principal object of the invention 1s to provide a t1le or monolithicunit of the above description which is strong, light and cheap, andprovided with-a suitable groove in its face into which a nailing stripor block can be readily inserted.

The above and other objects and the novel features of my invention willbe apparent from the following description taken in connection with theaccompanying drawings 1n which,

Figure 1 is a erspective View lllustrating a block embo ying myinvention and to which base or other trimmings may be secured;

Fig. 2 is a horizontal section of the block taken on the line 2-'2 ofFig. 1;

Fig. 3 is a perspective view of another block embodying my invention andequlpped with nailing blocks or strips for partitiondoor jambs;

Fig. 4 is a transverse section of the block shown in Fig. 3 taken on theline 4-4 of Fig. 3.

Referrin' to the drawing and Figs, 1 and- 2 in particu ar, 1 haveillustrated a building block or tile 10 made of clay, gypsum or othersimilar material. The block is preferably formed with a continuous claypress and has two large cells 11 and 12' and a smaller cell 13 betweenthe two end cells. The cells 11, 12 and 13 extend from end to end of theblock and rovide a hollow monolithic structure whic is light and doesnot require much material.

One of the outer faces of the block 10 has a groove 14 therein whichextends longitudinally of the block parallel to the cells and isdisposed midway between the lateral faces of the block. The groove 14has undercut edges 15 on opposite sides of the center and isconsiderably deeper than the thickness of the lateral walls of thecells. The groove 14 is formed simultaneously with the cells 11, 12 and13 .when the material is forced through the die of the press and theblocks are out off in the desired lengths. The

groove extends into the body of a block and is disposed between thelarger end cells 11 and 12 and opposite the smaller cell .13.

The groove 14 is designed to receive a nailing stripor block 16 which isprovided with inclined sides corresponding to the inclination of theundercut edges 15, 15 of the groove 14. The nailing strip 16 ispreferably driven endwise into the groove of the tile 10 after thelatter has been dried and burned and is held in place flush-with the.face of the tile by means of the undercut edges 15. The nailing strips16 may be of Wood, fiber or other suitable material and are preferablytreated with creosote so that they will not be warped or affected bymoisture from the plaster. The nailing strip 16 may be-readilydriveninto place by-a carpenter or other builder. The base boards 18, m ay benailed directly to the strips 16 or may be nailed to furring strips 19which the upright nailing latter are nailed to strips 16.

In Figs. 3 and 4 I have illustrated another hollow tile 20. embodying myinvention which is adapted for partition door jambs.

This form of tile or block eliminates the use.

of bucks for partitionsiand has a central cell 21 and two end cells 22and 23 which extend longitudinally of the block from end to end thereof,the cell 21 being larger than the end 1 cells 22 and 23. The block 20 isprovided with the undercut grooves 24 and 25 in the opposite facesthereof and adjacent opposite lateral edges of the block. The grooves 24and 25 are similar to the groove 14, extending throughout the length ofthe block and having portions thereof projecting into the. body of theblock opposite the smaller cells 22 and 23 respectively. The depth ofthe grooves 24 and 25 is considerably greater than the width of the cellwalls and these grooves are provided to receive the nailing strips orblocks 26 and 27. The strips 26 and 27 are inserted endwise into thegrooves 24 and 25 and are in all respects similar to the strip 16 shownin Fig. 1. s

The tile 20 is particularly adapted for use as a partition door j ambtile to which the up-- rights 28 of the door j amb 29 may be nailed.

Nails may also be driven through the door jamb into the outer ends ofthe nailing 3 strips 26 and 27 as the inner ends thereof will abutagainst other tile and prevent the strips 26 and 27 from being drivenout of the grooves 24 and 25.

s It will be noted that thecells 22 and 23 of Fi' 4, like the cell 13 inFig. 2, are considera 1y smaller thanthe larger cell or cells of theblock since they are in that part of the block opposite the grooves.Each of the smaller calls has one side thereof in line with a side ofthe adjacent larger cell and there is a groove back-to-back with eachsmall cell and disposed on the other side of the wall 019-. posits thatside of the cell which is in line all kinds of wood work usually nailed,se-

cured or wired. to masonry work. The tile may be used for basetrimmings, wide jamb linings, chair rail, and. for fastening any othertrimmings, or' special fixtures and for many other purposes. I

The tile is adapted to be made cheaply by machinery and it will be notedthat the walls of all the-cells are of uniform thickness throughout,except that those walls between the undercut or slanting sides of thegrooves and either the adjacent cells or drying or in burning.

Having thus'describedthe invention what out the length of the outerfaces-of the blocks, as shown in Figs. 1, 2, 3 and 4, are slightlythicker in parts thereof. It will be noted that those walls ofthesmaller cells parallel to the narrow ing block in the groove. This isan important feature ofimy invention as the tile made in this way willshrink, dry and burn uniformly. fIf made with walls "which are notsubstantially of the same thickness the tile would otherwise crackto'pieoeswhile is c1aim'edis':*":- g g v A hollow= building tile consistingof a body of rectangular form" in cross section hav1 gthre'e passages.extending therethro gh from endgto end, the middle one of said assages"being separated from opposite fiices of the tile by walls ofsubstantially the same thickness as those between the several passages,and the other two passages being 0 smaller area than the middle passageand each separated from one face of the sides of the tile will beadapted to receive driving thrusts transmittedfrom the nailtile by a.wall of approximately the same thickness as those between said passagesand separated from the opposite face of the tile by a much thicker wa 1,said thicker walls being'respectively on opposite sides of the tile andeach having formed in its outer face an undercut groove"extendingthroughtile to receive a nailing strip.

In testlmony whereof I lfix my signature.
